BINDING-POST.

SPECIFICATION forming part of Letters Patent No. 781,686, dated February'7, 1905,

Application filed November 24,1902. Serial No. 132,515.

To all 10/1/0111 it may concern:

Be it known that I, CLARENCE C. Smear, a resident of Perth Amboy,Middlescx county, New Jersey, have invented certain new and usefulImprovements in Binding-Posts, of which the following is aspecification.

The object of my invention is to provide a binding-post to which anelectric conductor or wire may be readily connected and quicklydisconnected therefrom and wherein also perfect electric contact will bemaintained; and to this end I provide a post with a head, and betweenthe post and the head is located a wireretainer consisting of a springor plate having an edge or end adapted to engage the conductor or wire,which firmly binds the conductor to the post and yet permits its readydisconnection therefrom.

The invention also contemplates the novel details of improvement thatwill be more fully hereinafter set forth and then pointed out in theclaims.

Reference is to be had to the accompanying drawings, forming parthereof, wherein Figure l is a side view of a binding-post embodying myinvention. Fig. 2 is a similar view looking from the side opposite thatshown in Fig. 1. Fig. 3 is a plan view thereof. Fi 4; is a side view)artlv in section. F1

a l b 5 is a section on the line 5 5 In Fig. l. Flg.

6 is an end view of the post with the head and retainer removed. Fig. '7is a detail view of the retainer. and Fig. 8 is a perspective viewthereof.

Similar numerals of reference indicate corresponding parts in theseveral views.

The numeral 1 in the accompanyingdrawings indicates a post, which may beof suitable construction and metal, and the same is provided with a head2, and between said head and the adjacent edge of post 1 is a spaceadapted to receive a conductor or wire 3, which may be bent around thestem 4, that connects the parts 1 and 2. The head 2 may be on a screwconnected with post 1 and which forms the stem 4, or the head 2 and thestem 4. may be made integral or permanent with post 1.

5 indicates the conductor or wire retainer, and it consists of a springor plate which is located in the space between post 1 and head oppositeend 0 2 and is shown of substantially ring-like form and resting uponthe end of post 1. The end 5 of retainer 5 is bent outwardly toward thehead 2 in the nature of a prong and adapted to engage the conductor orwire 3, that is passed under the head 2, (see Fig. 2,) and the of theretainer 5 is bent downwardly and passed into a slot 1 in the end ofpost 1. whereby said retainer is held from r0- tating around stem 4 andis maintained under the head 2. by preference also the retainer 5 isbent or raised on the side opposite the end 5, as at 5, to assist incrowding the conductor or wire 3 against head 2. The end 5 of retainer 5is preferably sharpened to grip the conductor or wire 3. When the head 2is movably connected with post 1, as by the screw-stem 4, the width ofthe space between the head and the retainer 5 may b adjusted toaccommodate conductors or wires of different gage; but when the head ispermanently connected with post 1, Fig. i, a somewhat limited range ofconductors or wires are provided for.

The post 1 being connected with any suitable part or element in acircuit, the conductor or wire 1 is placed between the head 2 and theretainer 5 and may be bent around the stem a, whereupon the sharpenedend 5 of the spring-retainer 5 will bear lirmly against the conductor orwire and will force the same into firm electrical contact with the head2, and the end 5* of the retainer will act like a dog to prevent thepulling back of the conductor or wire. The bend or extension 5 of theretainer 5 also serves to crowd the conductor or wire against the head 2when the conductor is bent around the stem (See Fig. 1.) It will usuallynot be required to adjust the head 2, because the bindingpost willpreferably be made as adapted to certain sizes of conductors, andtherefore it is obvious that the conductor or wire may be readily andquickly connected with the binding-post by merely making one turn or'apartial turn of the conductor or wire around the stem 4. To detach theconductor or wire from the binding-post, it is simply necessary to pullthe conductor or wire3 sidcwise from engagement with the end 5 of theretainer 5.

Having now described my invention, what I claim is- 1. The combinationof a metal post having a head and stem, a retainer in substantiallyannular form having an opening .leading through one side and located inthe space between the post and the head and provided with a sharpenedend or prong projecting in the direction of a conductor and adapted toengage a conductor, and means for preventing the retainer from rotationon the post, substantially as described.

2. The combination of a post having a head and a space between the postand head, with a spring-retainer having one part bent to engage aconductor, and another part bent and located in a slot in the post,substantially as described.

3. The combination of a metal post having a head and a space between thepost and head, with a spring-retainer having its end sharpened andprojecting in the direction of a conductor adapted to engage a conductorand having a bent portion at a distance from said end to engage saidconductor, the latter being bent around the post to engage the retaineron opposite sides, substantially as described.

4. The combination of a post having a head and a space between the postand head, with a spring-retainer having its end adapted to engage aconductor and having a bent portion at a distance from said end toengage said conductor, and also having a bent portion entering a slot inthe post, substantially as described.

5. The combination of a metal post, a head thereon and a stem betweenthe head and post providing a space for a conductor to be bent aroundthe stem, with a spring-retainer having its end sharpened and bent inthe direction of the conductor to engage the conductor, and means forholding said spring-holder to the post, substantially as described.

6. In a binding-post, a spring-retainer having one end bent to engage awire and its opposite end bent to enter a slot in a post and having abend or enlargement between its ends to engage the Wire, substantiallyas described.

7. In a binding-post, a spring-retainer in substantially annular formhaving an opening leading through one side to receive a stem and havingone part bent to engage a Wire and another part bent to enter a slot ina support, substantially as described.
